Abstract (en)
[origin: WO2010114438A1] A two stroke crank case scavenged two-stroke internal combustion engine, the engine including: - a cylinder (2) configured to reciprocatingly receive a piston (6) therein defining a combustion chamber (8), the combustion chamber comprising an ignition means (5) for igniting an air/fuel mixture and an exhaust port (40) for evacuating the exhaust fumes, - a crank case (3) including a crank shaft (18), - an indirect fuel supply system (4), such as a carburettor (12) or a low pressure fuel-injection system, for supplying fuel to the crank case (3) to be scavenged to the combustion chamber (8), - at least one transfer duct (20, 20') each extending from the crank case (3) to at least one corresponding transfer port (21, 21') for connecting to the combustion chamber (8), - additional air filling means (25, 24, 27, 23, 23', 22, 22',26, 26') for at least partly filling the transfer duct/s (20, 20') with additional air from the transfer port (21, 21') towards the crank case (3), - and a direct injection means (7) for injecting fuel directly into the combustion chamber (8).
